Abstract (en)
[origin: WO2011043772A1] A scheme for managing security key architecture in a network environment where a user equipment (UE) device can engage in multiple security contexts depending on the access technology. In one embodiment, when multiple security contexts are engaged and different sets of authentication vectors are created, an adapter component of the UE device manages potential interference that may be caused among the different sets of the authentication vectors as to where they are stored and which authentication vectors are used for service handovers.
